Subject: [PATCH 1/1] tracing: fix spelling mistakes
Fix some spelling mistakes in comments:
wont ==> won't
overwite ==> overwrite
outputing ==> outputting
overlayed ==> overlaid
singe ==> single
The name of an unused function parameter:
ingore ==> ignore
And the name of the cpuhp step:
preapre ==> prepare

The ring buffer has its own internal recursion. Although when

+ recursion happens it won't cause harm because of the protection,
but it does cause an unwanted overhead. Enabling this option will
place where recursion was detected into the ftrace "recursed_functions"
file.
